Loading all classes on classpath

Hello!
I'm trying to create some kind of "Package browser" which I can use for selecting a class that exists on the classpath.
I've come up with a solution that reads the classpath property and then looks up the classes by searching each directory and jar-file for class files. These are presented in a JTree. This solution has a drawback though. When using Visual Age for Java, my app won't find any class files on the classpath as these are not added to the local file system. It seems Visual Age has it's own ClassLoader which loads classes from it's own repository rather than from the file system.
Now I wonder, is there another way to load all classes from the classpath?
Regards,
Pelle Poluha

Visual Age uses the "system" classpath alright. When I add another directory to the classpath using VA, my "package browser" recognizes this but shows an empty directory. And it is empty on my local file system. What I can do is to export all the classes I need to a directory or jar-file and then add this to the classpath. Then my app recognizes the classes. But this is too cumbersome.
What I need, I guess, is a way of communicating with the current classloader and get it to return all classes/packages in a given package. Anybody knows if that's possible?

Pelle Poluha

Problem loading modified classes from CLASSPATH using system class loader

Hi,
I am facing problem to load the modified classes from CLASSPATH.
I have set my CLASSPATH to a directory whose classes will be modified frequently. After the server(web/app) is started, the system class loader, using which am trying to load the classes from the directory where the CLASSPATH is set, am not able to load the modified files without the server restart.
Do I need to have a custom class loader to fix this.
Please help me.
Thanks,
Sureddy

Do I need to have a custom class loader to fix this.Yes.

content server is running standalone.
Anyone knows why?
Thanks.

Java.sql.Date and java.util.Date - class loaded first in the classpath

I had two jar files which has java.util.Date and java.sql.Date class file. i want to know whether which class is loaded first in the classpath...
I like to change the order of loading the class at runtime...
Is there is any way to change the order of loading of class...
I may have different version of jar files for example xerces,xercesImpl. some of the code uses xerces ,some of the code uses xercesImpl..i had common classes.
I like to load the class with the same name according to the order i need..
Can we do all these in Run time ?????

The classes you are referring to are part of the Java API. Third party jars have no impact on that. And you can't change to the order because java.sql.Data is derived from java.util.Date. So the second must load before the first.
And if you have two jar files with those classes in them (and not classes that use them) then you either should already know how to use them or you should stop trying to do whatever you are doing because it isn't going to work.

How to load a class , which isn't in the classpath environment variable.

Hi, you folks.
I have one problem. I want to load a class, which isn't in the classpath
environment variable and I don't want to put into classpath. which method
JVM can use to load it?
Waitting for your sage advice.
Regareds
Hunter.Xiao

You will have to write your own ClassLoader, or use something like URLClassLoader (I've never used this myself, but I've seen it mentioned elsewhere in this forum). Look here.

How to load all the classes in a JAR file at runtime?

Any clues o:
"How can I force JVM to load all the classes in a specified JAR at once?"
Thanx!
-Rajeev

Well I was thinking may be there exists an option with "java", when I
am starting an application from a jar file, I could force it to load all
the classes in the JAR. I don't want to do it programically. Is there such
an option available?? Or in other words can I ask JVM to not do the dynamic
loading for the JAR??
Thanx.
List all JarEntries and convert the paths to fully
qualified class files
e.g file in jar
[1] /com/mycompany/proj/X.class
should become
[2] com.mycompany.proj.X
then for each entry issue
Class.forName( [2] );

Loading a class from specified classpath

Hello,
I would like to create an instance of a class in a specific directory.
So, I am doing this way :
System.setProperty("java.class.path", classPath.getAbsolutePath());
Class object = Class.forName(name);
Object instance = object.newInstance();It works perfectly when running in my IDE (Eclipse).
But when I am running my application through a JAR, I encountered the following error :
ClassNotfoundException
I don't understand why an exception is thrown whereas I defined correctly my classpath.
Could you help me ?

When running from an executable jar the normal class path is ignore in favour of thejar and any Class-Path specified in the jar's manifest.
What you want is a URLClassLoader. Bascially:
URLClassLoader cl = new URLClassLoader(new URL[]{classPath.toURL()});
Class clazz = cl.loadClass(fullName);(Catch assorted exceptions)
There should not be a class of the given name in the jar, or libraries it references (if there is, that will be loaded in preference).

Loading a class not on classpath

how can we load a class not on classpath?

uddinr0121 wrote:
try this
private void addArchive(File jarFile) throws IOException {
URL u = jarFile.toURI().toURL();
URLClassLoader sysloader = (URLClassLoader) ClassLoader.getSystemClassLoader();
Class<?> sysclass = URLClassLoader.class;
try {
Method method = sysclass.getDeclaredMethod("addURL", parameters);
method.setAccessible(true);
method.invoke(sysloader, new Object[]{u});
} catch (Throwable t) {
t.printStackTrace();
}this will add the jar file to the classpath after which you should be able to invoke using Class.forName()
hope this helpsThat's a horrible solution, when you can just create a new URLClassLoader and use that to load the class.
Adding it to the system classpath with reflection trickery is not really a clean solution to that.

Determining all classes available in the classpath

Hi,
I'm trying to recreate some functionality an ex-colleague of mine wrote some time ago!
Basically, he wrote (or found) some code that trawled through the whole classpath in order to discover all classes that were implemented a certain interface.
In that instance, this was used to check for all availible Datasource implementations so that we could "auto-detect" any new jdbc drivers that a customer may add to the classpath.
This solution is more for convenience - I've inherited a 900 file project and need to be able programmatically determine which of these are servlets.
Can't work out how to get a complete Class[] - I know how resolve the rest of the problem!
Thanks for any thoughts and suggestions.

You can use Javadoc API.
Write a small "doclet" that prints for each class of your project what interfaces it implements and from what class it derives, or simply tries to check (via instanceof) if the class implements javax.servlet.Servlet.
com.mycompany.legacy.MyServlet extends com.mycompany.legacy.MyFrameworkGenericServlet
com.mycompany.legacy.MyFrameworkGenericServlet extends javax.servlet.http.HttpServlet
javax.servlet.http.HttpServlet extends javax.servlet.GenericServlet
javax.servlet.GenericServlet implements javax.servlet.Servlet

LoadClass (error loading a class which extends other class at run-time)

Hey!
I'm using the Reflection API
I load a class called 'SubClass' which exists in a directory called 'subdir' at run-time from my program
CustomClassLoader loader = new CustomClassLoader();
Class classRef = loader.loadClass("SubClass");
class CustomClassLoader extends ClassLoader. I have defined 'findClass(String className)' method in CustomClassLoader.
This is what 'findClass(String className)' returns:
defineClass (className,byteArray,0,byteArray.length);
'byteArray' is of type byte[] and has the contents of subdir/SubClass.
the problem:
The program runs fine if SubClass does not extend any class.
If however, SubClass extends another class, the program throws a NoClassDefFoundError. How is it conceptually different?
Help appreciated in Advance..
Thanks!

Because i'm a newbie to the Reflection thing, i'm notI don't see reflection anywhere. All I see is class loading.
sure what role does the superclass play when i'm
trying to load the derived class and how to get away
with the errorWell... hint: all the superclass's stuff is not copied into the subclass.
I am quite sure it fails to load the superclass because of classpath issues.

All classes that are in the system class path are loaded by the

Problems using JAXB in windows(Failed to load Main-Class manifest)

Friends,
I am trying to use JAXB in windows environment. I have already included rt and xjc jar files in my system classpath.
I have sucessfully created java files using the xjc compiler(without the xjs map file). They rock!!
But I am facing problems while creating .xjs file from my dtd. I tried looking into previously discussed topics, with no help. :(
my command line:
java -jar C:\jaxb-1.0-ea\lib\jaxb-rt-1.0-ea.jar mySchemaFile.dtd
This is what i get :
Failed to load Main-Class manifest attribute from
C:\jaxb-1.0-ea\lib\jaxb-rt-1.0-ea.jar
Please help, if you have come across this or similar issue..
Or let me know how you create a .xjs file.
Any idea what is the main file class in jaxb-rt-1.0-ea.jar that creates a xjs file ?
All/any help appreciated. Thanks in advance.

Hi,
You cannot use xjs files with the JAXB Beta RI.
This has been mentioned at http://java.sun.com/xml/jaxb
"Note that this version is not API-level compatible with the previous released version of the specification and DTD schemas are no longer supported."
You can generate code using the xjc binding compiler for schema documents.
Pls let me know if you have more questions
Thanks,
Bhakti

JSPServlet: Exception: oracle.jsp.parse.JspParseException: line number 18, <%@ taglib uri="/includes/TTT_TagLib.tld" prefix="ttt" %>
Error: Unable to load taghandler class: /includes/TTT_TagLib.tld
The deploy of the same ear under Linux platform with the same iAS version ( 9.0.4 ) is working fine.
Any idea?

Hi all,
CLASSPATH in windows is D:\oracle\mtierAS10g\jre;D:\oracle\mtierAS10g\jlib;D:\oracle\mtierAS10g\jre;D:\oracle\mtierAS10g\rdbms\jlib;D:\oracle\mtierAS10g\network\jlib;
CLASSPATH in Linux is equivalent
